What causes penile itching?

Penile itching may be caused by poor personal hygiene, dry skin, genital herpes, balanitis, contact dermatitis, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analysis is as follows:

1. Poor personal hygiene: Failure to clean the penis regularly or change underwear in a timely manner may lead to bacterial growth, resulting in penile itching. It is advised to maintain good personal hygiene habits, wash the penis daily, frequently change undergarments, and choose breathable fabric for underwear.

2. Dry skin: Dry climate or use of irritating cleansing products can easily cause dryness of the penile skin, leading to itching. It is recommended to use mild cleansers, avoid excessive washing, and apply moisturizing creams to keep the skin hydrated, which helps relieve dryness.

3. Genital herpes: This is usually caused by factors such as trauma or viral infection. Herpes lesions can stimulate local nerve endings, causing itching and blisters on the penis. Patients are advised to follow medical instructions and use medications such as valacyclovir hydrochloride tablets, acyclovir tablets, and mupirocin ointment.

4. Balanitis: This may result from unhygienic sexual activity, phimosis, or other factors. Inflammation often stimulates surrounding tissues to produce increased secretions; if not cleaned promptly, these may accumulate within the foreskin cavity, causing itching, redness, swelling, and pain in the glans penis. Patients should follow medical advice and use medications such as clotrimazole cream, miconazole nitrate cream, or amoxicillin granules.

5. Contact dermatitis: This may occur due to allergic reactions triggered by exposure to chemical cleaners, new underwear materials, or similar substances. The condition can cause persistent irritation to the penile skin, leading to the aforementioned symptoms. Additional symptoms may include a burning sensation or pain. Patients are advised to follow medical guidance and use topical treatments such as calamine lotion, compound dexamethasone cream, or acetic acid prednisone cream.

In daily life, patients are encouraged to maintain regular作息 (sleep-wake cycles), avoid staying up late, and engage in moderate physical exercise such as jogging or playing badminton, which helps promote blood circulation and reduce the risk of disease.
